Food Crop Production by Smallholder Farmers in Southern Africa:
Challenges and Opportunities for Improvement evaluates traditional
cultivation practices used by smallholder farmers, providing a
synthesis of the latest information on increasing crop yield
through adoption of research innovations. The book catalogs
smallholder cultivation practices and recommends innovative
strategies for improving the agriculture sector including:
management practices that reduce net carbon emissions; technologies
that improve soil structures and conserve the natural resources
base; means of empowering female resources along value chains; and
government commitment to adopt policies that enhance agriculture
productivity by encouraging farmers to use environmentally sound
cultivation technologies. Traditional farming techniques often
produce negative impacts on the environment and ecosystem resulting
in outbreaks of diseases and pests. In addition to the region's
recurrent droughts, these outbreaks of numerous diseases and pests,
weeds and other invasive plants put thousands at risk of poverty
and hunger, as well as malnutrition. This book presents enhanced
agricultural production technologies for ensuring adequate food
production, safety and nutritional quality for the population of
Southern Africa and forms the basis for an increased SADC regional
effort in food production through which financial and trade
institutions can improve stakeholder capacities, encourage
micro-enterprise development and enhance employment and regional
trade.
Sorghum is one of the world's major cereals, cultivated in the
semi-arid tropics for a growing range of uses. Like other crops it
faces the need to meet rising demand whilst reducing its
environmental impact and adapting to the challenges of climate
change. This volume summarises the wealth of research addressing
these challenges. Part 1 explores the genetic diversity and
genomics of sorghum. This provides the foundation for Part 2 which
reviews advances in conventional and marker-assisted breeding and
their use to develop high-yielding and stress-resistant varieties.
The final part of the book discusses ways of improving cultivation
to make the most of new varieties, from nutrient and water
management to better control of diseases, insects and weeds. With
its distinguished editor and international team of expert authors,
this will be a standard work for cereal scientists, sorghum
breeders and growers as well as government and non-government
agencies supporting sorghum cultivation. It is accompanied by a
companion volume which reviews the range of uses of sorghum and
cultivation in different regions.
Sustainable Recovery and Reutilization of Cereal Processing
By-Products addresses topics associated with the sustainable
management of cereal manufacturing. Emphasis is placed on current,
advisable practices, general valorization techniques of cereal
processing by-products, and the functional properties of healthy
cereal by-product components that lead to target applications in
foods and nutraceuticals. Focus includes discussions on wheat bran,
distillers' dried grains-based within the biorefinery concept, and
different techniques for the separation, extraction, recovery and
formulation of valuable compounds, including proteins,
arabinoxylans, and beta-glucan.
Plant Micronutrient Use Efficiency: Molecular and Genomic
Perspectives in Crop Plants presents information on the complex
mechanisms regulating micronutrient use efficiency in plants.
Understanding this science is essential for the development of new
varieties of crop plants that are more resilient to micronutrient
stress, as well as plants with increased bioavailable
concentrations of essential micronutrients. This book explores the
discovery of novel genes and key metabolic pathways associated with
micronutrient use efficiency in plants, gives an analyses of the
gene expression patterns in plants in response to low and/or high
nutrient levels, and investigates the potential functions of these
genes and their products. Strategies to enhance micronutrient use
efficiency and stress tolerance, to develop bio-fortified crop, and
to improve the sustainable utilization of natural resources are
critically evaluated. The book contains both fundamental and
advanced information as well as critical commentaries that are
useful for those involved in the various fields that make up the
plant sciences.

"The result is a beautiful book with a lot of useful and updated
information. I am sure it will be in great demand, and hopefully
will help in the further improvement of cassava yields, especially
in Africa where it is such an important food crop." Dr Reinhardt
Howeler, CIAT Emeritus; author in: Achieving sustainable
cultivation of cassava Volume 1 Originating in South America,
cassava is now grown in over 100 countries around the world. It is
the third most important source of calories in the tropics after
rice and maize. Its caloric value, as well as its ability to
tolerate dry conditions and poor soils, makes it a key food
security crop in developing countries, particularly in Africa. As
demand for food grows, there is an urgent need to increase yields
in the face of such challenges as climate change, threats from
pests and diseases and the need to make cultivation more
resource-efficient and sustainable. Drawing on an international
range of expertise, this collection focuses on ways of improving
the cultivation of cassava at each step in the value chain, from
breeding to post-harvest storage. Volume 1 starts by reviewing
current issues facing cassava cultivation around the world before
discussing methods for sustainable intensification such as
rotations, intercropping and more efficient nutrient management.
Achieving sustainable cultivation of cassava Volume 1: Cultivation
techniques will be a standard reference for agricultural scientists
in universities, government and other research centres and
companies involved in improving cassava cultivation. It is
accompanied by Volume 2 which reviews breeding, pests and diseases.
Preharvest Modulation of Postharvest Fruit and Vegetable Quality is
the first book to focus on the potential yield quality, quantity
and safety benefits of intervention during growth. Of the many
factors responsible for overall quality of produce, about 70
percent comes from pre-harvest conditions. Written by an
international team of experts, this book presents the key
opportunities and challenges of pre-harvest interventions. From
selecting the most appropriate growing scenario, to treating plants
during the maturation process, to evaluating for quality factors to
determine appropriate interventions, this book provides an
integrated look at maximizing crop yield through preventative
means. In fact, with the very best of postharvest knowledge and
technologies available, the best that can be achieved is a
reduction in the rate at which products deteriorate as they
progress through their normal developmental pattern of maturation,
ripening and senescence. Therefore, it is very important to
understand what pre-harvest factors influence the many important
harvest quality attributes that affect the rate of postharvest
deterioration and, subsequently, the consumers' decision to
purchase the product in the marketplace.

Increase in world population, extreme weather conditions, decrease
in fresh water supplies, and changes of dietary habits are major
issues that affect global food security. We are expected to face
the challenges of land use by 2050 because population will reach 9
billion while agricultural productivity losses are expected due to
overuse of lands. How can we feed the next generations in a manner
that respects our finite natural resources? Managing our resources
in a sustainable way have only begun for selected crops. Much
remains to be done to increase food yield. Cropping practices
capable of sustainable production need to be elaborated, especially
in fragile ecosystems. Typical applications will include the
improvement and use of genetic resources; crop management and
diversification; diffusion of improved varieties; development of
cropping systems; sustainable cropping systems for areas prone to
environmental degradation; use of agro-ecological data for crop
production forecasting; and networks for regional coordination, and
data exchange. The impetus behind this book is to bring attention
to a cropping system that bears direct relevance to sustainable
agriculture and food security. "Underutilized" crops are found in
numerous agricultural ecosystems and often survive mainly in
marginal areas. It is timely to review their status because, in
recent decades, scientific and economic interests have emerged
which focus on lesser-known cultivated species. Underutilized crops
have a great potential to alleviate hunger directly, through
increasing food production in challenging environments where major
crops are severely limited. "Global Perspectives on Underutilized
Crops" is therefore topical and highlights the unmet agricultural
challenges that we face today. This book is an important resource
for students and researchers of crop science and agricultural
policy makers.
Biotic Stress Resistance in Millets presents an important guide to
the disease and pest-related challenges of this vital food crop.
Biotic stresses are one of the major constraints for millet
production, but newly emerging and forward-thinking problems with
disease and insect pests are likely to increase as a result of
changing weather, making this an imperative book on best practices.
Current strategies are mainly through the development of resistant
cultivars, as the use of chemicals is cost-prohibitive to many of
those producing millet in developing countries where it is of most
value as a food source. This book explores non-chemical focused
options for improving plant resistance and protecting crop yield.
This single-volume reference will be important for researchers,
teachers and students in the disciplines of Agricultural
Entomology, Plant protection, Resistance Plant Breeding and
Biotechnological pest management.
The research and its outcomes presented here focuses on
tropospheric or ground level ozone, in particular due to its
surfacing as a major threat to crop productivity around the world.
This book presents the ozone concentration data for a variety of
geographical regions, examines the factors responsible for its
increasing concentrations and its potential effects on
physiological and biochemical responses culminating in crop
productivity losses which, in turn may pose a serious threat to
global food security. Beside this, certain ameliorative measures
that could be adopted to assess ozone injury in plants are also
discussed. Global climate change scenarios predict a significant
increase in future tropospheric ozone concentration. Particular
attention is therefore given to evaluate the effect of global
climate change on ozone concentrations. Readers will also discover
how yield losses due to ozone are related to changes in the
socio-economic conditions of the society, especially in South Asian
regions. Students and researchers studying crop and soil science,
environmental scientists, risk assessment professionals and policy
makers will find this book of interest.
The book covers the latest development in the biosciences field
covering key topics in crop improvement including 'omic approaches
to improving sustainable crop production, advancement in marker
technology, strategies in genetic manipulation, crop quality and
sustainability and plant microbe interaction detailing on proven
technologies to address critical issue for agricultural
sustainability which are beneficial for researchers and students.
The book also includes aspects of preserving crops after harvest as
this is a key factor in promoting sustainable crop quality in terms
of addressing waste, choosing the appropriate packaging and moving
crops through the food and industrial supply chain. An important
strategy to overcome the challenges in providing food for the world
population in a sustainable manner is through concerted efforts by
crop scientists to embrace new technologies in increasing yield,
quality and improving food safety while minimizing adverse
environmental impact of the agricultural activities. Most of the
proven molecular and genetic technologies in crop science have been
tested and verified in model plants such as Arabidopsis and tomato.
The technologies, when deployed on various plant species of
importance for human nutrition and industrial applications,
including cereals, vegetables, fruits, herbs, fibre and oil crops,
face many challenges, not only due to their longer life cycle but
many other physiological and environmental factors affecting yield
and quality of plant products. Furthermore, major impacts on crop
production due to catastrophic diseases and global climate change
needs urgent and innovative solutions. Therefore a systematic
approach, employing various leading-edge technologies that enable
the functional elucidation of key pathway genes via 'omics tools,
genome wide association with desired phenotypes and development of
cost effective and practicable molecular tools for selection, is
vital. The International Conference on Crop Improvement was held to
address these and other pressing issues. This volume summarizes the
keynote presentations from the meeting and highlights addition
discussions that are critical to crop improvement in a challenging
time.
This book reviews the current state of knowledge concerning cacao
pathogens and methods for their management. Topics discussed
include the history, biology and genetic diversity of
Moniliophthora species (which cause witches' broom and frosty pod
rot) and Phytophthora species (which cause black pod rot) that
cause diseases resulting in major losses to cacao production.
Emerging pathogens such as Cacao swollen shoot virus and
Ceratobasidium theobromae (which causes vascular streak dieback)
are also discussed in detail, along with many pathogens of
significant local concern. Most of these pathogens represent major
risks to global cacao production should they expand into new areas,
breaking out of their current limited distributions. By considering
cacao diseases as a group, similarities in the available tools and
techniques used in their management become apparent, as do their
limitations. Gaps in our current knowledge of cacao pathogens and
the management of the diseases they cause are detailed, and
suggestions for future research directions are provided. This
insight allows readers to consider cacao disease threats from a
more comprehensive, global perspective and paves the way for an
improved synergy of efforts between the various research programs,
agencies, and industries, both private and public, with vested
interests in cacao production, and cacao farmers.
